You'd finally known what peace was after the war against Voldemort was done, things in life for you was quite blissful. You were dating the most kindest and caring guy on the planet, a literal cinnamon roll who was none other than Neville Longbottom himself. You never thought he'd have a dark side to him but unfortunately that's where you went wrong. We all have a dark side in ourselves, some are able to mask it completely and make sure it never surfaces on our personality and some are not

Neville still didn't know how he managed to date someone so beautiful and kind as you. Well, he DID know a little bit, looks like all those nights at Hogwarts at keeping a watchful eye out for you making sure you're safe(More like stalking the living daylights out of you that is), keeping rotten people like Malfoy away from you and protecting you from the Dementors and Death eaters and all that. When it was time for the wizarding war you were hell bent on fighting and helping out but Neville was having none of it, he wanted you to be safe and that was all that mattered to him. He didn't want you fighting and so he decided to keep you safe by asking his grandmother to look after you

He couldn't allow you to Apparate by yourself, what if you ended up at the wrong location? So with some gentle cajoling, pleading and coaxing from his side, he managed to get you to his grandmother's house. After the war was done, you thanked Neville and his grandmother for keeping you safe and he told you it was no problem. You started dating him after a while and he felt like life was pure bliss for him. Everything was perfect, he had the most beautiful girl in the world with him, things were all right. Now, he wanted to marry you and have kids with you, because one: He always wanted a family with you and he felt you'd make a great mother. And two: He's also worried someone will steal you away from him, even though he slayed Nagini with the cool badass looking Gryffindor sword, he's still a bit insecure of himself and he often wonders why someone like you is still spending time with him and is together with him. His insecurities will eat him up and chew him inside which will enable him to take action

Neville tried to talk to you about marriage before but the thought kind of freaked you out a bit. You couldn't help but feel bad when you saw Neville's downtrodden and sad puppy look on his face though, he could always tug your heart strings, it was like a talent of his or something. "I don't know Neville... I'd like to focus on my work for now, and I think it's too soon. But you can be assured that I won't leave you, I promise'' you smiled at him. Neville's grandmother wasn't making things easier for him either, she wanted you to marry Neville. "Don't let a woman like her get away from you, you need a bright woman like her in your life. Make her agree before someone else steals her away from you''

You didn't realize Neville started cutting you off from your friends and family slowly. He knows it's a horrible thing to do but you just need to see that Neville can provide for you and he can be a really good husband to you and love you. He's also blinded with his immense love and affection for you that he's now unable to see what he's doing is wrong. You both are destined to be soulmates and he's convinced about that, no power in the world can change his way of thinking now. You felt lonely so you started spending more time with Neville which he was really happy about. You don't need other people than him, he can look after you and he'll treat you like the precious flower you are

You finally agreed to marry him when you thought you were ready. If you'd seen the red flags and the warning signs your life wouldn't have become so difficult. Neville proposed to you in a really cute way, he took you out for a date at a fancy restaurant and with the help of his grandmother and his besties, Harry, Ron, Hermione, Seamus, Dean, Ginny and Luna he planned a really romantic proposal for you. There was soft jazz music playing at the background setting a calm ambience around. You said yes and Neville's happiness knew no bounds. You got the dream wedding you've always wanted and Neville was on cloud 9, he had you as his wife. But he was still worried about you leaving him so the only thing that'll bind you both together is a family, having kids with each other

Neville doesn't want you exhausting yourself with work anymore, he's happy to provide for you. He knew it was wrong to mess with your birth control and hide your pills but he really wanted a family with you. He'd give anything to see a little one with the same features of you and him running around the house, or little ones. Neville would be a really good father, just trust him
